The supplier asked me to move all chats and transactions out of Alibaba.com, should I follow that?

If you bought at Alibaba.com but the supplier asked you to move all chats and transactions out of the Alibaba.com, you are suggested to keep all chats, communication records via email, Whatsapp or WeChat and other evidence well in case you open a dispute if something goes wrong with the order later. Also, you are suggested to do business online through Trade Assurance order, or it might be difficult to protect your rights and interests.
